X-Men Cinematic Universe - Timeline (Revised & Original)

Naw. The Logan connection was definitely intentional.

In regards to the "No new mutants born after 2004", I mean, as an estimate yeah. There would be 1% of leftovers in the next generation; possibly why the New Mutants were so special to begin with.

Also, very often are species declared extinct only for years later for them to pop up again and thus no longer extinct but still endangered.
Life finds a way but for the most part, Mutants are mostly gone in the generations after 2004 regardless.
